Shrub rose plant named &#39;Poulren019&#39;

ABSTRACT

A new garden rose plant of the shrub class which has abundant, deep pink, fragrant flowers, and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

BOTANICAL DESIGNATION

Rosa hybrid

VARIETY DENOMINATION

‘Poulren019’

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of gardenrose plant which originated from a controlled crossing between thefemale seed parent, an unnamed, non-commercial seedling, and the malepollen parent, also an unnamed, non-commercial seedling.

The two parents were crossed during the summer of 2001 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulren019’, originated as a single seedlingfrom the stated cross.

The new variety may be distinguished from its female seed parent by thefollowing combination of characteristics:

1. The seed parent has smaller flowers than ‘Poulren019’.

2. The seed parent has light green foliage while the foliage of‘Poulren019’ is dark green.

‘Poulren019’ has more abundant flowers than the male pollen parent.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

1. Uniform and abundant red-purple flowers;

2. Vigorous, but compact growth when propagated both as a budded roseand on its own roots;

3. Exceptional disease resistance;

4. Fragrant flowers.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulren019’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 2001 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark. ‘Poulren019’ was selected in thespring of 2002 by the inventor as a single plant from the progeny of theaforementioned hybridization.

Asexual reproduction of ‘Poulren019’ by traditional budding and rootedcuttings was first done by Mogens N. Olesen in the nursery inFredensborg, Denmark in July, 2002. This initial and other subsequentasexual propagations conducted in controlled environments havedemonstrated that the characteristics of ‘Poulren019’ are true to typeand are transmitted from one generation to the next.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color illustrations show as true as is reasonablypossible to obtain in color photographs of this type, the typicalcharacteristics of the buds, flowers, leaves, and stems, of‘Poulren019’. Specifically illustrated in the drawings are: openflowers, flower petals, reproductive parts, stems, and leaves showingjuvenile and mature growth.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulren019’, as observed in itsgrowth in in a field nursery in Jackson County, Oregon. Observed plantsare 3 years of age, and were grown on Rosa multiflora understock. Colorreferences are made using The Royal Horticultural Society (London,England) Colour Chart, 2001, except where common terms of color areused.

For a comparison, several physical characteristics of the rose variety‘Pouldra’, U.S. Plant Pat. No. 12,999 are compared to ‘Poulren019’ inChart 1.
